How many carbon dioxide molecules are present in 1.5 moles of carbon dioxide?

To determine the number of carbon dioxide (CO₂) molecules in 1.5 moles, we can use Avogadro’s number, which is approximately 6.022 x 10²³ particles (atoms or molecules) per mole.

We simply multiply the number of moles by Avogadro’s number:

1.5 moles x 6.022 x 10²³ molecules/mole = 9.033 x 10²³ molecules.

So, there are approximately 9.033 x 10²³ molecules of carbon dioxide in 1.5 moles of carbon dioxide.
